I need help with my rsm hwrk pls help me

Step-by-step explanation:

When we consider Area under arc AC is is representing a quarter as ADBC is a square, .

Area of quadrant =

here r= 8 cm

Area under Arc AC=

Area of white region ABC = Area of square ADBC - Area under Arc AC

Similarly , Area of white region ADC =  

Area of shaded region = Area of square - Area of white region ABC - Area of white region ADC

Area of shaded region =

Length of arc AC =

Perimeter of shaded region = 2(AC) =

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
